Hi I'm trying to get a new USB-WLAN stick (blue media BM-5531) running using ndiswrapper (netmw226, 64bit-windows driver) and wpa_supplicant. During this action I stopped the interface (/etc/init.d/net.wlan0 stop) and finally removed the USB-WLAN stick. Perhaps due to some misconfiguration my running kernel (linux-2.6.21-gentoo-r3) produced an oops: The kernel is still running (at least for the next 24 hours) because there is an ongoing world rebuild ... modprobe -r ndiswrapper hangs too.

From upstream: 1. try rmmod before unplugging 2. describe what chipset 3. where to get the driver from For 2. google says "Chipset: Marvell 88W8338 + 88W8010", but better verify this info too. Not much I can do here, please post answers to these questions on ndiswrapper forum ( http://ndiswrapper.sourceforge.net/ ).
2) yes, the BM-5531 has this chipset, but I have to use the driver from a ZONET ZEW2502 (which has the same chipset) due to the lack of 64bit drivers in the BM5531 driver package. > Not much I can do here, please post answers to these questions on ndiswrapper > forum ( http://ndiswrapper.sourceforge.net/ ). I agree but I found this oops at least mentionable.
